The invention discloses a lifting platform based on a trolley for an elevator load test, which comprises a chassis and a carrying platform, and further comprises a central driving mechanism and a closed-loop lifting unit, and the closed-loop lifting unit comprises a lifting trolley, a lifting middle column and a pair of scissor arms symmetrically arranged between the chassis and the carrying platform. The scissor arms comprise a chassis scissor arm and a carrying scissor arm; a lifting middle column is further fixedly connected between the chassis scissor arm on the left side and the chassis scissor arm on the right side. The lifting trolley is arranged on the upper surface of the chassis in a front-back sliding fit mode, a pair of vertical base plates extend on the lifting trolley, vertical guide grooves are formed in the vertical base plates, and the lifting middle column is sleeved with the vertical guide grooves. And the output end of the central driving mechanism is in driving connection with the lifting trolley. The device is reasonable in structural design and flexible in movement, adopts a guide rod sliding block mechanism as a control mechanism, can achieve the stable lifting of the carrying platform, and facilitates the improvement of the detection efficiency of an elevator load test.
